1986 200x Build-Up

[250ES5984]

I had posted in input thread before, just specifically for before I followed through with the buy, but now I feel the need to start a build thread.

I purchase a 1986 Honda 200x from a guy in Tuscaloosa that said he needed to get rid of it. When I talked to him, he said he had gotten it in a box. It had had a bent exhaust valve and had jumped time, so he put new valves, timing chain, and timing chains gear in it. That's all he said that he did. He had mentioned that it smoked when it got hot, so I figured it was gonna need a top end overhaul anyway.

When I got to his house, he mentioned that the kicker was messed up when he got it, so he done some "custom welding." Needless to say I needed a new kicker.

I rode it around, and it smoked. Endlessly. I figured that was okay too since I was getting it at a decent price.

I pulled out of his yard with a 200x worth, I think, more than 1000.

I'm getting the engine rebuilt by Dales Cycle Shop in Iuka, Ms. I have a choice on some different pistons, and specifically don't want the compression of a Wiseco. He gave the option of a Shindy kit, with a .06 over bore, that he already has in stock. Any more or better ideas for kits would be appreciated as I will not be able to get him to rebuild it until later in June.

I would get the wiseco 10.25:1 piston. the increase in compression would go from 9.2:1 to 10.25:1. that would be about 1-2hp difference. if done correctly with support mods, you can hit 4-5hp. this would include upgrade to 28mm carb (mikunis are great), performance good quality exhaust (Supertrap, Bassoni, ETC. DG sucks.....), performance intake filter with either no lid on the airbox, or holes drilled.
just so you know, none of this is rocket science. this is a minimum I always do to 200X's I come across and work on and this is standard for most riders.
you will also want to put in a heavy duty clutch and spring set for longer lasting clutch.

Where do you think I could find a better exhaust than a dg? I've looked around and on ebay and can't seem to find anything other than dg. and what is the bore size for a 10:25:1 piston? I cant seem to find a wiseco kit with that compression.

ebay. take your time. may take you a month or 2, but you can get one.
also post in the classifieds you want a performance header for the 86/87 200x. then you can always get the muffler later. you can also o to a performance shop and have them modify a J-bend to fit and help build you a custom head pipe. if you take a decent muffler ( bassoni, supertrap, even stock CRF250r), with you they can install it on the trike as well. you want to go no more than 1/4" diameter larger than stock ID or you ill start to hurt performance unless building a stroked rad setup then 1/2" max.

Also, I would strongly advise AGAINST jumping right to a .060" overbore! I would tear the engine down and measure to see what bore it is on now and only bore to the next size. Overboring is not a mod done for performance really, it's main purpose is to restore a cylinder to specs for taper, bore (piston/cyl clearance), and out of round. Boring more than one step is un-necessary and IMHO foolhardy, especially in the case of a 2nd gen 200x where good used parts are less abundant. Yes you can re-sleeve, but why saddle yourself with the extra cost of a sleeve and the shop labor to install it sooner than is necessary.

I wouldn't be too concerned about the Wiseco 10.25:1 piston. I would just stay away from the 12:1 unless you want to run race fuel. Wiseco pistons are good quality and given a choice between those and some ebay chinese knock-off, I would go Wiseco every time.

You might want to contact Mickey Dunlap at 4-Stroke Tech. http://www.fourstroketech.net/#!__products/honda/vstc1=atc-86%27-87%27-200x

While he only lists an 11:1 piston for a 2nd gen 200x, he may be able to offer some help for other alternatives.

That's a nice looking 2nd gen! And given the overall condition of it, I think you are right about what it's worth...At least in my area.

dome chamber design. Wiseco sells the piston. they cut their domes to fit both chamber designs so they work on both years. their site tells you they fit 83-87

you will want to get the next larger sized piston so have the stock measured to see if it had been replaced before. if not the next size would be a 65.5mm (stock is 65mm), or even a 66mm. don't go for the 12:1 as your putting around not racing and will probably not want to do all the head work needed to run that piston correctly.

Yea, I definitely don't want the 12:1. The guy that I am getting to do it was going to do a 66.5mm bore with a Shindy flat top piston.

Now Im leaning toward a Wiseco, I just ain't very excited about the cost. Lol

OK a couple things: I don't know about Shindy pistons, but I have used Shindy valves based on some advice I received here. I was told they are Japanese made (which is a good thing as opposed to Chinese) and that the quality is there. I was pleased with them and would use them again in the absence of OEM parts availability. Based on that, I would suspect their piston quality is good as well and I would give them a try if the circumstances pointed me in that direction.

Next: Why is the shop guy pushing you toward a 66.5 bore? Is this based on pulling the top end and measuring what it currently is and determining the 66.5 to be the next size over what it is now? Or is he wanting to do that because that's what is on his shelf??

If you haven't yet pulled the top end to figure out what bore it is currently on, I would not make any decision on the overbore size until you do. And it goes without saying, for the bore job to be correct, it must be done with the new piston on hand to match the bore to. You can't simply look at stock cylinder dimension specs and go "X" over that and expect it to be right. The piston must be on hand and measured, and then the bore must be done based on the piston dimensions to set proper piston/cylinder wall clearance. If it's not done this way you could seize it up the first time you start it, or have a "new" top end that still smokes like a 2-stroke..

Also, remember to check and set ring end gaps to spec. This too can be critical. If too wide you will be down on compression and may be burning oil. If too tight, the ring gaps can close completely when the engine is brought up to temp causing the rings to seize.

[250ES5984]

I think I may go ahead and get the piston before I take the trike to the mechanic. The motor, from what I can tell and have been told, has a stock bore.

Shortly after my first post, I received a set of repop tank shrouds and a new to me light and engine shut off switch from tx200m.

I had told the owner that I wanted satin black on all of it, but soon after I left, I remembered that I had wanted gloss black on the skid and kicker and gloss white on the hubs. I'll probably fix that later down the road, as paint isn't that big of a deal yet.

I still have to find a performance header and silencer.

Another thing, what is the best way and the easiest way to cut down the vibration in the bars? Anywhere that I can ride around here I have to go down highway, and the vibration is getting unbearable.

Don't buy a piston until you mic the bore. You are putting the cart before the horse. If I were you I would pull the jug and send it to John Tice. He will set you up correctly.

Yes you will get help.

Buying a piston without knowing for sure what size you need is not a good idea. With a 30 year old machine, it's anyone's guess as to what size the bore is regardless of what someone says it is. Most pistons will be marked as to what size they are. Standard pistons will have either no markings or in the case of most aftermarket pistons will be marked "STD". Overbore pistons will be marked in thousandths or mm over. All you should need to do is pull the head and clean the top of your current piston enough to see how it's marked. Once you do, order a new piston the next size larger.

Okay, would it be easier for me to pull the motor completely out? I think I may end up getting the frame powdered when all of this does happen. Just a thought though, as I don't know if I can take it all apart, then put it back together. Lol

do NOT powder coat the frame till everything else is done. that should be one of the last things you do. you have to install parts and test fit stuff (you will nick and scratch it if you do). I also recommend you have a shop gusset the frame for you. it will re-enforce the tubing connection points so they do not crack and brake on you. bot pretty when that happens..

biggest thing, TAKE YOUR TIME!!! my 350X build was in the planning stages for 7 months before I even turned 1 wrench on it. take your time, research and spec things out.

Timing just about any Honda engine is a piece of cake once you know the procedure, which is pretty simple really.

Good idea to do a complete valve job along with the fresh bore and piston. A new piston and cylinder bore running back up at new condition compression can and often does expose or accentuate shortcomings with valves, seats, and valve seals that have alot of run time on them. Sounds like you are on the right track for doing this job right the first time, and I think you will be well pleased with it when done. :beer

Thanks. So, the Mikunis are just as good as the stock Keihn carbs? I haven't been able to find an aftermarket exhaust other than a new DG/RCM. would there be any point in getting one, or would I do better if I just wait?

What are the racing advantages to the slides vs. rounds? No, I don't plan on racing it, although I'd actually like to. There's nowhere around here that has had or do have trike races. May be able to get access to a track though.....

[oscarmayer]

oh yea, and there are a ton of jet kits available for jetting them too. less expensive as well.

slides are more instant response over round, so you get a faster throttle response, but they are harder to tune than the round.
I would keep scouring eBay for a super trap or bassoni pipe, fmf, ETC. even if you pay $200-$250 for a good system it is a deal. you can always blast and repaint it even if rusty so that is no biggie.

stick with the mikuni stuff for the carb, you will be fine.

I'm still trying to figure out what I want to do as far as the rebuild goes. I've found another bike and atv shop here pretty close and plan to call them tomorrow.

I really would love to do it myself, but I'm afraid that if I do, I'd end up leaving something out or re-assembling something wrong.

Plus, I'd like to get the bottom end scoped out to see if the vibration problem is coming from the bottom end. I would like to also have the crank bearings checked just in case.

I'm thinking that if I can get this one rebuilt and fixed that I may try to rebuild my 250sx myself. Have a buddy that has a good bottom end that I can buy from him pretty cheap. Thinking that I could take my top end and put on his bottom end and make 1 good out of 2 bads, considering that his had a screwed up top end. Just throwing around ideas though, as I don't have the money.

Can you tell me any more about the powdercoater? Looks like decent work, good prices? Turnaround time? There is no one nearby that does it anymore...

$80 for everything that was coated. His turnaround is great! He had my stuff finished the next evening. When I got up there, his shop was full, so I'm gonna guess he's pretty quick. There's a guy in Muscle Shoals that I talked to recently, but his prices were outrageous.

Apparently flyingw on here does it, or did it, as well. I had meant to check in with him as well but never got around to it. May be something to look into.

After almost a year, I've finally got enough money saved up to get this project going. Trike is going to a mechanic today for teardown. He's going to mic the bore and let me know what size piston to get or order it himself, which is up to me.

Decided to go with a 10.25.1 Wiseco. Don't know about the bottom end as of yet.

Haven't talked to yaegerb in a while, still may get him to do the valve job if he has time, but don't know yet.

Got the Cobra exhaust. Not exactly what I wanted to use at first, but it's what I have for noe.

Updated as they come.

Bore turned out to be stock.

Just placed an order for the Pro-X 65.25 kit from Ebay, along with an All Balls carb rebuild kit, and Barnett Dirt Digger HD clutch kit.

Did a little reading and it seemed the the Pro-X kit were decent, and made in Japan. Any downfalls or problems from these?

I've heard good things from others about Shindy carb rebuild kits, but has anyone used the All Balls? Looks like they come with some extra o-rings that the shindy kits didn't come with.

The Barnett clutch kit seemed to be the beast way to go as far as a rebuild kit. Any problems from them?

Thanks, Chandler.

Well you could pay me an enormous amount of money for them :lol:

One of those guides matches the 85, the other, (Check Parts Unlimited), I'm not sure on the other.

If your looking for the (gear) part of cam well i suppose it looks like it is removable BUT to find a new (gear) i would think is near impossible. I dont think i've seen a worn out 86/87 cam gear. Cam lobes yes.
Yup new guides are $$$ you probably already know that.241161
Good luck, you gotta get it running for spring!!!!

So it seems like a number of parts are interchangeable between the 200x and sx. Are the motors the same?

Well, the top half is. Bottom end not so much just a couple small odds +ends.
Then you have the 86/87 fatcat , the 89-9? trx200d but the rockers dont have the decompression stub molded into them.

Ok, so with that said, would the timing chain guides interchange? I would think so myself unless something mounts different. If they will interchange, should the honda part number be the same?

The part #'s will be close i think the first five digits would be the same, then the next 3#'s would change per model.
If u try searchine those machines for the guides it wont work any better, but u may find trx's used guides are cheaper because some sellers dont know.

Shep

[250ES5984]

The guy building my motor for me called 2 nights ago and told me that the guides and tensioner were all okay, so that's one less thing to worry about.

Got my piston kit, gasket set, and carb rebuild in yesterday. Just waiting on clutch kit.

Stupid me forgot to order a right cover gasket when I ordered the clutch kit, so still have that to do along with ordering a timing chain.

Where or what brand is a better chain? Have looked at them on Honda parts warehouse, bike bandit, and motorsport.com. just curious if one is any better than any other.

Thanks, Chandler.

Thanks Shep. I appreciate all of the advice. Just ordered the timing chain you linked.

It seems you're pretty knowledgeable when it comes to the 86 and 87s.

More updates as they come.

Well, I've looked over some of your posts and I think I seen a YouTube video of the green framed bike? Just knowing that you've built one or two already means you know a lot more than I do about them.

[Shep1970]

Oh ya the green framed bike, let me tell you its been all winter and i still haven't got (picked out a seat cover)
Too many choices out there. One of these days though- nice weather is coming, the last of snow here is gone.
Sooooo if u need a seat cover DONT ask me. Ha

Tell me this, there is a set of 86 timing chain guides, tensioner, and chain on ebay for 50 bucks. Would it be worth my time to get them for that price just in case? Seems like a great price for all of it.

[Shep1970]

I'm probably the wrong one to ask-but for that price i'd walk away. i know an 86 was just parted on ebay and the parts look really clean and most of it sold within a couple days if not as soon as he listed it. If your planning on keeping the bike just start scoping out ebay a few times a day at odd times. In a few years you'll have lots of extra's. Just wait for the deals but the time of deals maybe over?
Shep

[250ES5984]

All I know is that I found a tensioner and that guide for over 100 a couple weeks ago.

[250ES5984]

Quick update. Guy that's rebuilding the motor for me let me know last week that I had something wrong with my exhaust valve. Did say what it was (bent, cranked, etc.).

So, I ordered a set of Shindy valves last Wednesday. Got them in the mail yesterday and took them to him. Said he was going to get it back together tonight.

Hoping to get it back this weekend if everything goes as planned. Haven't ridden it this year yet, so, I'm somewhat exited!

Another update. When he got down to put the clutch kit in, the mechanic found that someone had cracked the case and tried to jb weld it back together.

So, I just purchased a set of cases from Ebay. This project has turned into wayyy more than I hoped for. As far as I'm into it now, there's no sense in stopping. May end up going full on resto-mod.

eBay........

I kinda figured. I do know you have to buy and entire engine gasket set to get them. Guess it's not a bad idea to keep an extra.
Appreciate the response.

I have more gasket kits than I do heads, and I bet I have 10 heads.

I just wait for a Vesrah, Centauro (Italian made gaskets that fit super well), or other brands to pop up for a good deal. And when I find the deals, I usually buy every single one that they have :lol:

I've never paid more than 35$ for a complete gasket set. These shops close, someone buys all the parts and they probably think, " hmm, three wheelers, not too many of them out there". And they show up dirty and dusty but factory sealed...

With all this new racing coming up, these things might get even more expensive!!

Dennis Kirk use to have a tensioner guide kit. One of the 85 tensioners fits the 86 correctly; Probably the one that just sits in a groove and not the one that mounts with a bolt to the case behind the oil filter rotor. Fortunately, the 86 doesn't even seem to get noisy with worn guides where the 85 sounds horrible when they're all clapped out...

[250ES5984]

Well, I finally have her back! Last week I had to get a new pressure plate for the clutch because someone had run the wrong bolts in it and had busted a piece on it.

Now, I have to put on my hubs, new shrouds, headlight/killswitch harness, and new seat bumpers and she'll be ready to go!
